2015 Mercedes-Benz 3 Series 2.1L Diesel · SS04 PRK

The vehicle remains roadworthy but the maintenance trend shows a recent shift towards mechanical wear and suspension component degradation. While the most recent test in July 2025 at 168,460 miles passed, it revealed thinning front brake pads and multiple suspension ball joint defects. This represents a regression from the clean record seen in June 2024, indicating that high-age components are now reaching the end of their functional life after years of use. The mileage accumulation is consistent with a 15-year-old vehicle, averaging approximately 11,200 miles per annum. The data shows steady usage, moving from 125,761 miles in March 2021 to 168,460 miles by July 2025. This consistent interval suggests the car has not sat stationary for long periods, which helps prevent internal fluid degradation, but it also places constant load on the rubber bushings and damping systems typical of an older Mercedes-Benz chassis. A buyer must prioritise a thorough inspection of the front suspension geometry, as the 2025 test flagged play in both the suspension arm ball joint and the offside anti-roll bar ball joint. These issues follow a documented history of shock absorber failure, progressing from reduced damping in 2022 to oil misting in 2023. The recurrence of these faults suggests the front-end assembly requires a comprehensive overhaul to ensure stability and prevent uneven tyre wear. The braking system also requires immediate attention as the July 2025 record noted pitted and scored front brake discs alongside thin pads. Given the previous advisories regarding perishing tyres in 2023, the buyer should also check the current rubber set for sidewall cracking and tread depth. While no structural corrosion has been flagged yet, the frequency of wear-related advisories indicates the vehicle is entering a phase where more frequent mechanical interventions will be necessary to maintain roadworthiness.
